Muddled mess (4)
I believe the answer is:
hash
'muddled mess' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hash that I've seen before include "Drug" , "Recycled food" , "reheated meat and vegetables" , "Meat dish; mess, jumble" , "Reheated dish" .)
